The Entropy Change Associated with the Expansion of One Mole

question 104

Multiple Choice

The entropy change associated with the expansion of one mole of an ideal gas from an initial volume of V_i to a final volume of V_f at constant temperature is given by the equation,ΔS = R ln (V_f/V_i) .What is the entropy change associated with the expansion of three moles of an ideal gas from an initial volume of V_i to a final volume of V_f at constant temperature?

• A)ΔS = R ln (V_f/V_i)
• B)ΔS = 3 mol × R ln (V_f/V_i)
• C)ΔS = R ln (V_f × 2³/V_i)
• D)ΔS = R ln (V_f × 3!/V_i)
